v1.87.5.0 perf: remove idle waits from tests and CI planning (#2897)

* v1.87.5.0 perf: remove idle waits from tests and CI planning

* fix: settle split PTY redraws before routing input

* docs: record final burst-safe test benchmarks

* fix: keep cold-setup snapshot metadata dependency-free

* fix: avoid early-reader pipe races in artifact URL parsing

* fix: preserve safety matches for multiline command payloads

* fix: recognize concurrent CSO publication removal

* test: preload the UI design-review target before invocation

* docs: record validation blocker fixes

* fix: bind plan observer rejection to the invoked command

* fix: count only native design decisions in the UI gate

* docs: clarify UI-positive eval evidence requirements

* test: recognize native UI decisions without weakening finding counts

* test: decouple native UI evidence from question punctuation

* test: recognize concrete native UI decisions independently of prose format

* fix: retain failed eval logs under the hidden CI cache

* test: await telemetry completion instead of racing disk writes
